The implicit promise of heap_alloc_caps() and friends is that the memory it
returns is fit for the purpose as requested in the caps field. Before
this commit, that did not happen; e.g. DMA-capable memory wass returned
from a correct region, but not aligned/sized to something the DMA subsystem
can handle.
This commit adds an API to the esp_mm component that is then used by the
heap component to adjust allocation alignment, caps and size dependent on
the hardware requirement of the requested allocation caps.
This return value is used by the tlsf_walk_pool
function to be notified of the need to interrupt
the ongoing traversal of the currently traversed
heap.
Introduce new APIs in essp_heap_caps.h:
- heap_caps_walk()
- heap_caps_walk_all()
Those functions are triggering a callback for all blocks
(allocated or free) of memory present in heaps meeting
the set of capabilities passed as parameter (or all heaps
for heap_caps_walk_all() function)
test_walker.c added to test the new functionality in
test_apps/heap_test/
Implement a function to start tracking the minimum free size from the
moment the function is called.
Implement a function to stop tracking the minimum free size and restore
the minimum free size value calculated since startup.
Implement the tests related to this new feature.
Add test configuration to run all tests with heap component in the flash.
Add reference to this new configuration in performance section of the documentation.
- Fix "test get allocated size"
- Add tests for the free / alloc hooks
- Call alloc function hook on malloc/realloc/calloc base functions
- Add caps parameter to the allocation hook function
- When PSRAM is enabled, the heap integrity check APIs
(`heap_caps_check_integrity` and `heap_caps_check_integrity_all`)
take more time to execute and keep the interrupts disabled for a
longer time.
This commit updates the chip independent system chapters of the
programming guide for esp32s3.

Configurable option to use IRAM as byte accessible memory (in single core mode) using
load-store (non-word aligned and non-word size IRAM access specific) exception handlers.
This allows to use IRAM for use-cases where certain performance penalty
(upto 170 cpu cycles per load or store operation) is acceptable. Additional configuration
option has been provided to redirect mbedTLS specific in-out content length buffers to
IRAM (in single core mode), allows to save 20KB per TLS connection.
